Hi,

 

Re: Key to Ray's New Arithmetics (Primary, Intellectual & Practical) by Mott Media

 

Just to let others know if they are in the same place as me, we spotted a mistake in the answers for Intellectual Arithmetic lesson 29 (XXIX) third part of Qu.9, ans should be 50/90 instead of 80/90. In lesson 30 (XXX), the first answer to question no.10, should be 1 1/10 instead of 4/5.

 

Well, at least one positive thing is it forces us to think and revise more and not take the answers for granted. I am changing some answers in the book, wherever any little space allows me to, but I think we need to create a new RA correction book.

 

If anyone comes across any more errors, please do let me know which questions they are.

 

Regards & God Bless!
